RESILENT TIRE-FILLING.

Specification of Letters Patent'.

Application filed August 20, 1913.

Patented Auga iii, 319ML. Serial No. 785,623.

To all whom t may concern:

Be it known that I, SAMUEL M. Bunny, a citizen of the United States, residing at- Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful improvement in Resilient Tire-F illings, of,wl1ich the following is a specilication.

My invention relates to an improvement in the construction of the resilient filling to be confined about the rim by the outer casing of an automobile-tire.

The object of my invention is to provide a tire-filling ot the kind referred to, which shall be simple and durable and shall effectively serve to resiliently cushion the load like the inner infiated tube of a pneumatic tire, but, unlike the latter, without'liability to be injuriously aii'ected bypuncturing.

' ln the accompanying drawings, Figure l y is a view in broken sectional elevation of a section of my improved resilient tire-filling; Fig. 2 is an enlarged view in cross-section of the filling confined in an outer casing, and Fig. 3 is a broken and partly sectional view of the annular filling looking at the inner periphery thereof.

To build the annular filling, ing my invention in the 'best form now known to me, I useV a central core e, for which a hempen rope is desirable, and sheath the core in a resilient tube 5, preferably of rubber-hose variety. A spiral spring 6 surrounds the tube 5 and is, in turn, enveloped in a sheath 7 of suitable fabric, such as canvas, which should be tacked, by one or more lilies of strong stitches, as represented at 8, to each convolution of the spring to hold it against creeping or buckling thereon.' About the canvas sheath is wrapped a longitudinally-split resilient tube 9, of the same material as the tube 5, and the edges are fastened together either by cementing them, or by means of lacin them together, as shown at 10, through eye ets 10 (Fig. 3) provided at intervals along the edges. The respective ends of the elements thus far described are suitably fastened together to reduce the whole to annular form. About the in embodytube 9 is wrapped spirally a strip of thick, 50 highly-flexible cushioning material ll, preferably felted wool, though other material for the purpose may be used without departure from my invention. 'the whole is then nrapped in an outer layer l2 oitl strong 55 fabric, preterablxcanvas, which is fastened in place at its edges.v as by a lace 13 passed through eyelets li therein (Fig. 3). The annular body thus formed is designed to be mounted on a suitable sectional clencher-rim t0 (not shown) of an automobile-Wheel and held thereon by an outer rubber-and-canvas casing 15 of usual or any suitable construction adapting it to be secured in place by the rim. I have devised a construction of sectional rim especially for securing an outercasing 15 over my present improved fillingbody. It is not illustrated herein, however, but forms the subject of my separate application for Letters Patent filed concurrently herewith on the 20th day of.Augnst 1913, Serial Number 785,622. The body thus formed when used on an automobile-wheel renders the latter easy-riding, being resilient in a high degree and effectively cushioning the load inpassing over obstructions, besides being comparatively light and desirable.

lVhat I claim as new and desire lto secure by Letters Patent is- An article of manufacture adapted to be used as a filler for tires, comprising a central solid core, having an irregular cross section, a resilient casing tightly fitting the outer surface of said core, the irregularities forniing air spaces' therebetween, a spiral spring the convolutions of which are spaced apart to provide asecond series of air spaces wound about said casing, a second resilient casing closely fitting about said spring, and a strip of light, flexible cushioning material wound about said casing, all of said parts bein in relatively close contact with one anot er, thereby to produce a compact resilient tire filler havin concentric l'air spaces.
